To correct myopia (nearsightedness) requires _ lenses; to correct hyperopia (farsightedness) requires ___ lenses to correct.

Myopia is an optical defect, in which a person can see nearby objects clearly and cannot see far off objects clearly.
Here the eyeball becomes too longer, and the focal length of eye lens become too short.
It can be corrected by using concave lens.
For Hyperopia, the person can see far off objects clearly and cannot see nearby objects clearly.
This can be corrected by using convex lens.

Thus, we can conclude that, by using concave lens, we can correct Myopia and Hyperopia can be corrected by convex lenses.

Myopia can be corrected using concave lenses, while the Hyperopia is corrected by convex lenses.

We need to be aware of myopia and hyperopia in order to locate the solution.

Myopia is an optical defect in which a person can see clearly up close but not clearly far away.

Here, the eyeball lengthens excessively and the eye lens focal length contracts.

A person with hyperopia can clearly see distant objects but cannot see nearby objects clearly.

Thus, we can deduce that myopia and hyperopia can be corrected using concave lenses and convex lenses, respectively.
